Thanks, Robert. That would work if I were compiling on the PB, but cross-compiling on my Debian VM was different. There may be an easier way, but what I did was follow this: http://phwl.org/2021/building-bbg-kernel/ to checkout the exact kernel I have on my PB, compile it, and then point my driver Makefile to this directory. This at least appears to work.
